A chemical reaction is endothermic if it absorbs heat from its surroundings. It is exothermic if it gives off heat to its surroundings. In her chemistry class, Lily is given a salt (ammonium nitrate) and a beaker of water at 60 โF. She dissolves the salt in the water and sees that the temperature of the solution is now 50 โF. Did the temperature of the solution go up or go down? By how many degrees? What kind of reaction has occurred?
